IEC 60204-11:2018 cancels and replaces the first edition, published in 2000. This edition constitutes a technical revision. This edition contains significant technical changes with respect to the previous edition regarding the following: - aspects of risk assessment, which are mirrored from ISO 12100; - equipotential bonding and earthing; - EMC and power quality; - HV switchgear and controlgear; - creepage distances for conductors and slip-ring assemblies; - a list of machinery using HV equipment, in Annex A. IEC 60204-11:2018 has been updated and improved to reflect the experience gained with the first edition and the evolution of high-voltage equipment reflected in the relevant standards. Regarding formal requirements, IEC 60204-11 has been aligned with - IEC 60204-1:2016, - IEC 61936-1:2010 and IEC 61936-1:2010/AMD1:2014, - IEC 62271 (all parts). This document is intended to be used in conjunction with IEC 60204-1.
